If so: Where is the wmr9-patch? Do you mean old quartz.dll?

This hint also helped me, so thank you Kevin,

but does anybody know why you have to have MP's priority set to high to resolve the stutter issues some experiences? This also has the downside if MP does something bad, its almost impossible to recover the system without a reset.

Seems to resolve stuttering issues also for me. I'm running MP with TVS3 in single seat. It was not necessary for me with the built in TVEngine. CPU usage is very low on m system (having a DualCore E4400 with 2 GB of RAM) so this seems to fix some latency issues.

Thanks for that hint.

Just tested it here myself and setting the priority to high fixes my stutter problem to. If you think about it it kind of logical. You always want the calculations of a movie or audio go first because its one of the most sensitive things to hear or see. Microsoft already build this in vista and xp for there own media players. Thats why there was the network bug when playing audio over from a remote share.

I've noticed the same problem somewhere since the rc1 release. Mostly on the news tickers and sometimes in movies when the camera moves right or left.

Since i made a complete reinstall of my system when i installed rc1, i figured it was a driver or decoder problem.

Tried diverent ati video driver versions and setting vsync to always on didn't solve it.
Ati avivo, pdvd7 and 8 decoders didn't made anny diverence.
Setting te priority to high as sugested in this (verry old) thread didn't either.

Finally solved it by running mediaportal on one core instead of both cores, should've tried that a lot earlier since i used to have major problems before with mp on both cores when tsreader (-use tsreader if i remeber correct) was stil in the test phase.

only problem with this is that you have to manually set it to one core on each restart of mp, wich is i'm glad to say only needed if i'm updating to a new svn. as mp runs rock solid

@nyria

If you want to run mediaportal only with 1 cpu core check my post here:

Flickering Tv-guide and other overlays with EVR enabled

Does this procedure work with every version of MP (i'm using RC1 with last SVN)? Is there a way to revert to dual processor affinity?

Thanks

pnyberg · 2008-06-16, 11:35

yes, as long as MP is started with mediaportal.exe it will work.
And yes you can run "sdbinst -u mediaportal_compat.sdb" to have dual cpu support again.
